Title: Sliding bearing
Inventor: DOI MOTOTATSU
IPC: F16C33/00
Filed: 1988-05-21
Abstract: PURPOSE:To prevent the seizure of a shaft and bearing at an oiling short time by arranging the member having an oil holding property provided so as to slide to the bearing face at the position apart from the part on which a rotary load is applied on the journal part of a shaft. CONSTITUTION:A shaft 1 holds a small gap with the inner peripheral face 2a of a bearing 2, penetrates through the bearing 2 inside, arranges the bearing 2 by fixing it to a housing 3 and feeds an oil from the external part between the outer periphery of the journal part of the shaft 1 and bearing face 2a. On the other hand, a recessed groove 1a is formed on the shaft 1 and the felt 4 of good oil holding property is arranged at the place apart from the position where the surface is projected from the outer periphery of the journal part of the shaft 1 and slided with the bearing part 2a and where a rotary load is applied on. Oil is thus fed to the bearing 2 inner peripheral face 2a with a surface tension and centrifugal force even if the oiling to the bearing 2 be short and the seizure of the bearing 2 of the shaft 1 can be prevented.

IPC: H04B10/293
Filed: 1993-05-26
Abstract: PURPOSE:To prevent spontaneous emitted light, generated in the latter stage of a light amplifier from exerting an effect on the processing stage of the light amplifier and to improve the upper limit of the amplification gain of the amplifier by a method wherein the reflection type optical amplifier is separated into two stages of the preceeding stage and the latter stage by an optical circulator having forward transmission characteristics from its terminal for inputting signal light. CONSTITUTION:An optical circulator 20 has forward characteristics from a terminal B to a terminal C and functions as one type of an optical isolator between the terminals B and C. As a result, spontaneous emitted light generated in a rate earth-doped optical fiber 15 is prevented by the circulator 20 and is not propagated in the direction of a rare earth-optical fiber 23. Thereby, it is eliminated that the preceeding stage (the side of the fiber 23 and a light reflector 24) of a light amplifier is affected by the latter stage, which consists of the fiber 25 and a light reflector 26 of the light amplifier and the light amplifier can obtain a high amplification gain as a whole.

Further, when the 3rd stage part 11c is positioned, averaged metering is performed. For variation in photodetector surface illuminance with diffusion characteristics, the diffusion part is formed on gray resin and decreased in thickness stepwise, thus reducing the variation greatly. Thus, numbers of metering ranges are switched by the simple structure.

Abstract: PURPOSE:To measure the angle of optical rotatory power at a high accuracy with a good response with an expanded measuring limit in a simple construction by making light passing through a Faraday cell several times with a reflecting mirror. CONSTITUTION:Light polarized linearly with a polarizer 4 passes several times, for example, three times, through a Faraday cell 5 made up a Faraday coil 52, a Faraday glass 5 and the like as reflected with reflecting mirrors 15 and 16, rotated angularly according to a sample of a sample cell 6 and received with a detector 8 via a light detection element 7 whose polarization plane differs by 90 deg. from that of a polarizer 4.

Title: Noise eliminating circuit and in-focus detecting circuit
Inventor: TAKAHASHI AKIRA
IPC: G01S17/10
Filed: 1980-09-09
Abstract: PURPOSE:To eliminate a large-level noise and to take a distance measurement with high precision, by determining the level of a digital signal by a noise eliminating circuit on the basis of frequencies of appearance of a high and a low level in a preset section. CONSTITUTION:An analog input is compared with a reference voltage ref by a comparator COM1 and converted into a digital signal having binary levels H and L. This signal is shifted by a shift register SR in response to the rise of a pulse phi2. A full-adder FA1 adds the 1st and 2nd bit outputs of the register SR, and a full- adder FA2 adds the 3rd bit output of the register SR, the sum output of the full- adder FA1, and a carry signal. The carry signals of the full-adders FA1 and FA2 are outputted through an OR circuit OR1, but its output signal is an H when >=2 bit outputs of the register SR are Hs. Therefore, when the digital signal has one H level out of three successive levels, it is removed as a noise. Thus, noises are eleminated and a measurement of distance is taken with high precision.

Title: Lead frame for semiconductor device
Inventor: KANEHIRO KAZUO
IPC: H01L23/50
Filed: 1982-07-19
Abstract: PURPOSE:To enable high density mounting by enabling to perform chip bonding and wire bonding under the optimum condition by a method wherein the die pad part and inner lead parts are coated with Au and Al respectively in a lead frame. CONSTITUTION:The Al coating thickness at the inner lead parts is preferable in 1-10mum, which is purposed to prevent the instability of wire bonding due to the mutual diffusion between Al and substrate tape at the time of chip bonding at 400-500 deg.C. While, Au coating at the die pad part 4 is purposed to form the Au- Si or Au-Ge eutectic crystal at the time of chip bonding. The Au coating is sufficient in the minimum thickness of 0.5-3mum whereby Au-Si eutectic junction can be performed securely and stably. From the viewpoint of cost, Al coating is more advantageous to the die pad part; but it is necessary to vapor-deposit them on a Au-Si eutectic alloy foil or a semiconductor chip in order to perform chip bonding, and it not only complicates the process in IC mounting but also is not preferable from the point of ohmic junction, thermal conductivity, and junction strength. Therefore, the lead frame manufactured by said method is hardly considered to be a good one, from the viewpoint of cost and quality in IC mounting.

Title: Measuring device for water content
Inventor: AIZAWA HIROSHI
IPC: G01N33/10
Filed: 1980-09-10
Abstract: PURPOSE:To enable to eliminate the necessity of sampling and also to measure water content accurately, by controlling flow-down rate of grains put into a tank from an intake port and allowing to flow down through a measuring passage. CONSTITUTION:When chaffed grains flow into a tank 1 as indicated by an arrow, they fall onto a receiving pan 6. The chaffed grains which have entered into the pan 6 are discharged from measuring passages 9a and 9c at a constant rate by means of rotary valves 13a and 13c which rotate intermittently. When the rotary valves 13a and 13c are stationary, the chaffed grains are in the state of repose in the measuring passages 9a and 9c, and at this time, hygrometers 10a and 10c measure water content of the chaffed grains staying between electrodes 11a and 11c and electrodes 12a and 12c. As this measurement of water content is conducted at a prescribed cycle by four hygrometers which are installed in parallel on the same level, it is possible to obtain even values of water content by averaging values measured by these hygrometers.
